About this supplement

Calcium Citrate Malate (CCM) is a highly bioavailable calcium salt formed by the reaction of calcium carbonate with citric acid and malic acid. It is a water-soluble compound specifically designed to enhance calcium absorption in the body, particularly in individuals with low stomach acid. CCM is widely used in fortified foods (like orange juice) and dietary supplements due to its excellent solubility and neutral taste. It is considered a superior source of calcium compared to other common forms like calcium carbonate, especially when taken without food.
